Changelog: [[Release2.2.0]]
|

|
|
|
|
|
|
The 2.2.0 release is primarily a performance and stability release. The code line represents development in the master branch since the release of 2.1.0 in Aug 2012 and therefore includes nearly a year of bug-fixes and optimizations. Nearly 500 new tests have been added bring the total coverage to 925. Shapefile and PostGIS datasources have benefited from numerous stability fixes, 64 bit integer support has been added to support OSM data in the grid renderer and in attribute filtering, and many fixes have landed for higher quality output when using a custom `scale_factor` during rendering. Critical code paths have been optimized include raster rendering, xml map loading, string to number conversion, vector reprojection when using `epsg:4326` and `epsg:3857`, `hextree` encoding, halo rendering, and rendering when using a custom `gamma`. Mapnik 2.2 also compiles faster than previous releases in the 2.x series and drops several unneeded and hard to install dependencies making builds on OS X and Windows easier than any previous release.

* This release attempts to maintain backward compatibility in the XML styling interface and will issue new deprecation warnings for any changes. See [[API-changes-between-v2.1-and-v2.2]] for details.

## 2.1.0
|
|
|
|
_2012-08-23_
|
|
|
|
|
|
|
|
Changelog: [[Release2.1.0]]
|
|
|
|
|
|
|
|
* This release includes significant refactoring in Mapnik core, with many new features like image compositing, geometry i/o formats, image-filters, and geometry clipping and smoothing. It has vastly improved map loading speeds and better rendering performance all around.

|
|
* This release attempts to maintain backward compatibility in the XML styling interface and will issue new deprecation warnings for changes. See [[API-changes-between-v2.0-and-v2.1]] for details.
|
|
|
|
* New datasource plugins include: [GeoJSON](https://github.com/mapnik/mapnik/wiki/GeoJSON-Plugin), [CSV](https://github.com/mapnik/mapnik/wiki/CSV-Plugin), and [Python](https://github.com/mapnik/mapnik/wiki/Python-Plugin).
|
|
|
|
* This release does not maintain full backwards compatibility in the python datasource API - notably the mapnik.Feature interface has changed slightly and now requires a mapnik.Context to be passed to the constructor.
|
|
|
|
* This release includes major refactoring of the TextSymbolizer, but should still be backwards compatible from XML and python.
